摘要
用不同原料和方法制备了不同类型的聚苯硫醚树脂.通过元素分析、红外光谱、激光拉曼光谱及X射线衍射分析等手段,对各种产品的结构进行了表征.对不同类型产品的结构差异进行了初步研究.结果表明,用不同的原料和方法都可制备聚苯硫醚树脂,各种聚苯硫醚树脂的结构基本接近。
Different types of poly(phenylene sulfide)s have been prepared with different materials at atmospheric pressure.The structures have been studied by Element analysis,IR spectrum,Raman spectrum and X ray diffraction spectrum.The results show that the structures of these PPSs are basically same,having only slight difference.The branched PPS and the oxygen cured/crossed PPS have cross link structure,the melt flow properties are poor.The linear PPS,high molecular PPS and modified high molecular PPS have higher molecular weight,good melt flow property and can be used in more extensive fields.
